Abstract: A tungsten and monlybedenum ore from Fujian contains mainly molybednite and wolframite as valuable minerals that are associated with pyrite. Beneficiation tests were made on this ore to provide a basis for its exploitation and utilization. The process consisting of preferential molybdnium flotation, sulfur flotation from the tailings of molybenium flotation and wolframite recovery by gravity separation was finally adopted through comparative tests, which obtained a molybedenium concentrate grading 80.77% at a recovery of 51.31%, tungsten concentrate grading 63.80% at a recovery of 68.31% and a sulfur concentrate grading 41.54% at a recovery of 97.67%, achieving a good comprehensive recovery of the valuable elements of the ore.
